摘要(Abstract)：

以来源于造纸黑液的碱木质素和草酸锌为前驱体采用原位碳化法制备了不同碳含量的木质素碳/氧化锌(LC/ZnO)纳米复合材料。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、紫外分光光度计(UV-Vis)、荧光光谱仪(PL)等对所制备的LC/ZnO的微观结构和光学性质进行了表征。结果表明所制备的LC/ZnO复合材料是由高度分散的ZnO纳米颗粒和木质素碳纳米片构成,表现出优异的紫外和可见光吸收性能。以常见的有机污染物罗丹明B为降解对象,在模拟太阳光的照射下对所制备的LC/ZnO复合材料的光催化性能进行了研究。结果表明,LC/ZnO复合材料的光催化性能明显优于纯的ZnO纳米颗粒和氧化石墨烯/ZnO复合材料,且在550℃炭化温度下所制备的LC/ZnO-550复合材料具有最佳的光催化性能。
